NFT collection floor-price lookup via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns the floor price for NFT collection #48 hosted on lowpaymentfee.com. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint `/api/v1/collections/48/floor` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The provider advertises no API keys, no rate limits, and instant access — you pay per call with no subscription or commitment.
Documentation beyond the landing page is extremely thin: the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint is live (returns a proper 402 challenge), but the actual response format after payment is unknown. The collection ID "48" is opaque — there is no published directory mapping collection IDs to NFT projects.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI spec, no request/response schema, no documentation, and no examples. The collection ID is opaque. Effectively a stub listing.

- —Collection ID 48 is opaque; no mapping to an actual NFT project is published.
- —All documentation pages (/docs, /pricing, /api, /README) render only a wallet-connect prompt with no content.
- —The broader platform lists many endpoint categories but this specific collections endpoint is not listed on the landing page, raising questions about its status.
